I would love Kane in Madrid, a superb striker.
Age is not such a big problem. Look at Benzema winning the ballon d'or at 35, Lewa top scorer in la liga at 34.
Three years would be ideal, with Vini and Rodrygo, with Endrick gradually coming into the team.
We could sell him for a decent price at 32/33 and back in England we would get the record.
The problem is that it clashes head on with the idea of going for Haaland in 2024, although on the other hand if Benzema leaves they have to look for a top level alternative, which could be Rodrygo as a striker and look for a right winger.
